Abstract: A process for producing a composite semipermeable membrane, which comprises coating a microporous support membrane with a polyamide formed by the interfacial polycondensation between a polyfunctional aromatic amine and a polyfunctional acyl halide. The polyfunctional aromatic amine component contains, as the comonomer component, 1 to 20 wt %, based on said aromatic amine, of at least one member selected from among alkyldiamine, 1,3,5-trihydroxybenzene and 1,3-dihydroxybenzene, and hence the resulting composite semipermeable membrane has markedly improved oxidation resistance while maintaining the excellent highly selective separative function and high permeability of a crosslinked polyamide type composite semipermeable membrane. This membrane can be suitably used for desalting of brine or seawater.

Abstract: The invention relates to a method and a device with which an FM or PM modulated signal can be detected from a carrier directly, without the disadvantages that the use of an analog or a digital phase lock will cause. The direct detection is realized so that the instantaneous frequency or phase of the input signal is measured by direct time interval measurement so that the time measurement resolution is increased by using a delay line. The detected result is already digital, whereby no separate analog-to-digital converter is required.

Abstract: A paging receiver has a synthesizer for governing the receive frequency. The paging receiver further has characteristics which are varied in response to the receive frequency. These characteristics include varying the bandwidth (52) of a loop filter (26) within a phase lock loop (16) within the synthesizer as well as varying the time in which a detector circuit used to extract a DC level from a recovered audio signal is disabled. Furthermore, the bandwidth of the loop filter is varied in response to switching from a first receive frequency to a second receive frequency in order to provide for either a uniform frequency lock time (54) or for a rapid frequency lock time. Furthermore, the time in which the detector circuit is disabled is correspondingly changed.

Abstract: A packing containment (10) assembly for sealing an operating member such as a shaft (12) or stem in a fluid control valve (14), particularly where PTFE packing (16) is used. A pair of zero clearance anti-extrusion rings (18) of PEEK material are mounted in the shaft with the PTFE packing (16) therebetween. Each ring (18) has an inner diameter slightly less than the shaft (12) outer diameter to form an interference fit. The rings (18) are split with a scarf cut (24) to provide an overlapping joint and enable mounting of the rings (18) on the operating member (12). A male adapter PEEK ring (64) matches a V-type female packing ring (16a) which significantly reduces the amount of PTFE packing (16) needed for a reliable seal. A step cut PEEK zero clearance anti-extrusion ring (18) could be used as well as a fractured carbon ring (50). <IMAGE>

Abstract: A reusable arrangement to protect against accidental contact with the sharp surfaces of needles and other invasive medical instruments. In one embodiment, the invention comprises a collar that engages a sharp surgical instrument in advance of its sharp end. Attached to the collar by means of a hinge is a slotted longitudinal member, which swings over the sharp end of the instrument, thereby engaging either the collar or the portion of the instrument just in front of the collar and also retaining the instrument behind a keeper shelf. The keeper shelf may be engaged with the opposite side of the longitudinal member to lock this member over the sharp instrument. The longitudinal member may also be equipped with wing members to facilitate movement of the sharp instrument around the keeper shelf. In another embodiment, the locking mechanism comprises a set of flanges depending from the longitudinal member that are gripped by complementary catches on the collar when the device is placed into the closed position.

Abstract: Device making it possible to remove the surgical cement from a femur in orthopaedics while minimising the risks of damage to the latter. It consists of a half-frame (2) having an opening receiving the reducing sleeve guiding the various tools (21-23-24). The said tools are five in number: a breaking tool (two sizes), three lips with apical angle 120 DEG , three reamers (two sizes), three lips of diameter 12 mm, 14 mm and 16 mm, and a finishing tool having small triangular teeth acting as a rasp. The frame is fixed on the femoral diaphysis by means of a symmetrical collet chuck, and it retains two movements in two orthogonal planes (frontal plane and sagittal plane). Thus, the guided tool can work in selected directions converging towards a point on the diaphysial shaft. The device according to the invention is intended in particular for the removal of cement when replacing a prosthesis in orthopaedics. <IMAGE>

Abstract: An integrated tunable optical filter comprising a substrate made of a semiconducting material. The substrate includes first and second sections. The first section forms a tunable transmission filter, based on a codirectional coupler having a low selectivity. The second section forms a reflection filter with a reflection spectrum containing a number of peaks. A first injector, designed for current injection into said first section, is provided. Thus, the filter response of the first section is shifted in wavelength over a large wavelength range. There is also a second injector, designed for current injection into the second section. As a result, the reflective spectrum of the second section is slightly shifted in wavelength, in such a way that one reflection peak of the reflection spectrum corresponds to the coupling wavelength of the first section. Consequently, the total filter response has a very narrow bandwidth and wide tunability.

Date Jul. 21, 1994.A device for tuning a combiner filter. The measuring signals (Prl . . . Prn, PF1 . . . PFn) of a number of different combiner filters are multiplexed to the same detectors. Multiplexing allows the measuring and adjusting electronics required by the tuning and adjusting means of combiner filters to be simplified considerably especially with a high number of combiner filters. Multiplexing of measuring signals is used primarily to select the sample signals of the forward and reflected power of one and the same combiner filter to be tuned for the measuring electronics. In the invention selectors for reflected power and forward power are independent of each other, which allows isolation measurement between different channels. The sample signal of the forward power of one combiner filter and the sample signal of the reflected power of another combiner filter are thus connected to the measuring electronics. When both sample signals undergo frequency-selective detection at the same frequency, the degree of isolation between the radio channels will be determined.
